Description
Technical field
The present invention relates to the preparation technology of a kind of activity dendrobium candidum freeze-dried powder.
Background technology
Dendrobium candidum is the perennial type herbaceous plant that grows nonparasitically upon another plant of the orchid family Dendrobium, for top grade in stem of noble dendrobium medicinal material, sweet with taste, matter heavy, the pliable and tough and big person of stickiness is preferred, and has effect of reinforcing stomach reg fluid, nourishing Yin and clearing heat, is clinically used for the diseases such as treatment pyreticosis Tianjin wound, deficiency of stomach-Yin, muscles and bones impotence be soft.The rich polysaccharide that closes of dendrobium candidum, alkaloid, the nutritional labeling such as amino acid, trace element, modern pharmacological research shows that it has the raising effect of waiting for a long time immune, hypoglycemic, anti-ageing.Dendrobium candidum is constantly excavated because having high medicinal efficacy and value thereof, and market development space and demand are very big.
Traditional using method of dendrobium candidum include fresh goods directly eat (as directly chewed, single decoct or with other medicinal material compatibilities, generation drinks tea) and drying or dry and be processed into Tiepi Fengdou；The former is fresh goods, there is nutritional labeling and preserve complete, nutritional labeling and medicinal function is unaffected and the advantage such as be easily absorbed by the human body, but it is difficult to preserve, easy mildew, and owing to institute's fibre-bearing and mucus are many, when chewing, mouthfeel is poor, and when decoction or tea-drinking, nutritional labeling is difficult to fried or dissolution, have impact on the use of fresh goods；Though the latter improves the inconvenience that fresh goods uses, but Tiepi Fengdou has a large amount of bast fiber because closing, and medicinal material is tough and tensile, there will be and is difficult to pulverize or pulverizes the problems such as incomplete, cause medicinal material to be wasted in Ordinary pulverization process.The market price of this raw material is of a relatively high, when being put into production, may result in cost and significantly strengthens, causes the unnecessary wasting of resources.
Therefore how making dendrobium candidum raw material obtain best application becomes the problem more paid close attention at present.Chinese patent disclosed some about the patent in terms of the cultivation of dendrobium candidum, compound formulation effect, but be also constantly in for dendrobium candidum material processing aspect the tradition stage.Therefore this is conducted in-depth research by my company.
Correlative study
It is being rich in nutrition again that the fresh medicine of the stem of noble dendrobium contains large quantity of moisture, and therefore very suitable micro-organisms growth, causes rotten.The drying long-term preservation being conducive to dried product of fresh medicine.Pertinent literature all shows that drying process all has impact in various degree to dendrobium candidum principle active component polysaccharide and dendrobine.This is also studied by we below.
Test by 4 kinds of common method-vacuum freeze dryings, hot air circulation is dried, tradition is dried, iron-sheet dendrobe fresh product is processed by method of naturally drying, the content by sulfuric acid-phynol method colorimetric method for determining polysaccharide for the dry product；Compare analysis with the content using gas chromatography detection dendrobine after chloroform extraction, thus select suitable drying means to provide reference for the fresh medicine of dendrobium candidum.
1 sample treatment
Fresh dendrobium candidum → clean → drain → be cut into segment → drying process
2 test methods
Take the fresh dendrobium candidum of the preprocessed mistake of equal in quality, be respectively adopted vacuum freeze drying, hot air circulation is dried, tradition is dried, naturally dry 4 kinds of modes is dried to safe aqueous rate (≤13% butt), measures the changes of contents of dendrobium candidum active ingredient polysaccharide and dendrobine.
It is dried process as follows:
2.1 vacuum freeze drying
Fresh dendrobium candidum being placed in quick-frozen 3h in ultralow temperature-60 DEG C of cabinet of frost, then condenser temperature-0 DEG C, being dried under conditions of vacuum 1Pa, its Drying rate is 21.1%, and water content is 6.52%.
2.2 hot air circulation are dried
Fresh dendrobium candidum is placed in heated-air circulation oven, at 50 DEG C, under conditions of air quantity 3400m3/h, is dried 7h.Its Drying rate 18.3%, water content is 6.92%.
2.3 tradition are dried
Fresh dendrobium candidum is placed in drying baker under the conditions of 80 DEG C, is dried 2.5h.Its Drying rate 19.2%, water content is 6.37%.
2.4 dry naturally
In the indoor ventilating, it is to avoid direct sunlight, utilizing air to circulate, making the moisture of dendrobium candidum be naturally evaporated to dryness dry, its Drying rate is 23%, and water content is 8.61%.
3 results
By the content of sulfuric acid-phynol method colorimetric method for determining polysaccharide, with high-efficient liquid phase chromatogram technique measuring dendrobine content.Result is such asFollowing table。
Polysaccharide content of dendrobium candidum
As can be seen from the table, under 4 kinds of drying modes, polysaccharide content of dendrobium candidum size is followed successively by: vacuum freeze drying ＞ hot air circulation is dried ＞ tradition drying ＞ and naturally dries (being dried dendrobium candidum moisture≤13%).
Dendrobine content
As can be seen from the table, under 4 kinds of drying modes, dendrobium candidum total alkaloid content is substantially suitable, show that dendrobium candidum alkali content is had no significant effect by different dry drying process, illustrate that its total amount during the aging death of stem of noble dendrobium plant of the alkaloid as plant hormone keeps constant.
Meanwhile, dendrobium officinale powder color and luster is also had a certain impact by different drying modes.Heating is bigger on the color and luster impact of dendrobium candidum dry product, hot air circulation is dried, tradition is dried and all be have employed heating, its on color and luster all in darker yellow green, with naturally dry, color and luster is dark compared with vacuum freeze drying, this is relevant with dry materials temperature height, and baking temperature is higher, and the brown stain situation of product is more serious, vacuum freeze drying product colour is more vivid, occurs without brown stain；Show that vacuum freeze drying product color is kept as preferably, hence it is evident that be better than other three kinds of drying modes.
In sum, using traditional dendrobium candidum medicinal material naturally drying method processing to become golden yellow, appearance character is good, consolidation, and the Drying rate of medicinal material is the highest, but polyoses content is relatively low；Hot air circulation is dried and tradition dries the medicinal material appearance character generation brown stain processed, and Drying rate is relatively low, and polyoses content is higher；The medicinal material of vacuum freeze drying processing, appearance character is good, consolidation, and the Drying rate of medicinal material is higher, and polyoses content is the highest.
Consider external and inherent quality, operability and the processing cost of processing medicinal material, use Vacuum Freezing & Drying Technology processing dendrobium candidum, the process reduces environmental pollution, the product water content simultaneously preparing is low, can preserve outward appearance and the active ingredient of dendrobium candidum best；It is more nearly new fresh goods after rehydration, avoid the features such as product surface hardening, nutritive loss and growth shelf-life,
Content of the invention
